The crewAI team released version 1.15.18, which promotes conversational flows to a stable status and enhances their documentation and APIs.

  • Promote conversational flows to stable
  • Map default Claude Sonnet 4.6 to its 1M context window
  • Raise Anthropic default max_tokens for large tool calls
  • Render message content parts as text, not as a Python repr
  • Clarify Arize Phoenix observability docs

This update stabilizes the conversational flow feature set and improves handling of specific model configurations and message rendering.
